'DUST M01?.

Application led January 27, 1922. SeraI No. 532,080.

T 0 all whom t may conce/rn:

Be it known that l, WILLIAM H. PLUNK- ETT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Tllinois, have invented certain new and useful Improvements in Dust Mops, of which the following is a specification.

This invention has reference to dust mops adapted for cleaning doors and other surfaces, mopsofthis general character beingsometimes called oil mops.

This invention relates to certain improve-- ments in the 'generaltype of mop disclosed in United States Fatent No. 1,155,564, granted October 5, 1915.

lt is a desideratum of mops of this character that the mop body or swab, as it is customarily termed, which is composed of fibrous strands, be readily detachable from the mop frame in order that it may be boiled and washed when requiredand also in order that'it may be replaced by a new swab when the old one becomes unduly worn.

One of the primary purposes of my present invention is to provide a mop comprising a detachable swab, which swab and the frame are so constructed that the swab may be quickly applied and securely attached thereto so that it will not become accidentally displaced but at the same time may be easily and quickly removed when occasion requires.

For the purpose of facilitating an understanding of my invention, I have illustrated in the accompanying drawings one embodiment thereof from an inspection of which, when considered in connection with the following description, my invention and many of its inherent advantages should be readily appreciated.

Referring to the drawings-F Fig. 1 is a plan view of the mop ing my invention;

Fig. 2 is a side' elevation thereof;

Fig. 3 is a perspective view of the mop frame;

Fig. 4 is a sectional view on the line 4--4 of Fig. 2;

Fig. 5 is an enlarged detail view ofone of the connections between the handle shank and the frame; and

Fig. 6 is a sectional view of the fastener by which the swab is detachably secured to the frame.

Referring now to the drawings more in detail, reference character 7 indicates genembodyerally the frame ofthe mop which,

preferred proportioned as as shown, is of general U-shape comprising the'fsubstantially parallel side members 8 and 9 joined at one end by a transversely extending cross member 11 forming a right angle juncture with the side members, the opposite ends of the` side members being bent outwardly in opposite directions to forni fingers which: can be introduced into crevices orbehind furniture legs and the like to enable the cleaning of surfaces which are ordinarily; inaccessible to the usual mop.

rThe handle vl2 has its. lower end inserted.

into Ythe circular portion ofr the'shank 153, which is. preferably formed of'sheet metal and bifurcated to provide the spacedv prongs or bifurcations 14 and 15 adapted to be disposed between the side members of the frame. These prongs are'connected to their respective adjacent side members by rivets 16, a fiat washer 17 being disposed outside the prong and a springwasher `18V being-positioned upon the rivet between such washer and its enlarged end 20. rlhis construct-ion provides a pivotal connection between the` handle and the frame permitting the handle to be swung into any desired angular position with respect to the mop body, and the` spring washers 18 impose such tween the handle shank and the frame that the mop body will be retained at any desired angle with respect to the handle which may be convenient for cleaning purposes.

The swab comprises an elongated binding portion 19, prefer. bly formed of fabric to which the inop strands 21 are fixedly attached. This binding is constructed to provide pockets closed at the outer ends of the binding and open at points remote from the ends into which the ends of mop frame are inserted, as will be apparent from Fig. 1. The central portion of the binding is provided with a latch adapted to cooperate with an aperture 22 formed in the frame cross member 11. This latch is best shown in Fig. 6 from which it will be apparent that it is in the form of a shank equipped at one end with a stud or rivet 23 adapted to be inserted through one or more layers of the binding 19 and through a washer 24 over which the ends of the stud are riveted to securely attach the fastener to the binding. The projecting shank portion 25 of the latch is so to be capable of insertion through the aperture 22, and in this shank portion there is pivotally mounted at 26 a friction ber latch member 27 shoulder 28 which in the elevated a spring 29.

In order to attach the mop swab to the trame the diverging lingers of the frame are introduced into the pockets as previously described` whereupon the central portion o1Ll the swab is pulled over the closed end of the frame and the fastener is projected through the aperture 22 until the shoulder 28 snaps upwardly intoengagement with the margin oi.t the aperture, thus locking the swab to the frame. Wlhen it is desired to rem'ove the swab the latch member 27 may be manually depressed to free the shoulder 28 'from the marginal wall oit' the aperture 227 whereupon the fastener may be withdrawn from this aperture so as `to free the swab from the frame. A

It will be apparent from the foregoing that I have provided a mop havingl a detachable swab which can be quickly applied to the frame and when applied is securely locked thereto against accidental displacement. Vhen removal is desired it may be effected by simply manipulating the latch member, whereupon the swab may be detached from the frame. The connection bctween the handle and the frame is strong and durable and aords sufcient friction provided with a locking member is normally held position shown in F ig. 6 by to hold the member in any desired adjusted position.

l claim:

l. A mop7 comprising a substantially U- shape frame having an aperture therein and having the ends of its side members bent outwardly away from each other, a mop swab provided with pockets adapted to receive said trame ends, and a latch carried by said swab and adapted to be detachably engaged with said aperture to lock said swab to 'the frame.

A mop, comprising a Ushape frame including a pair of side members united at one end by a cross member joined at right angles to the side members and provided with an aperture, a swab attached to said side members, and a resiliently urged locking device secured to the center of the swab and adapted to enter said aperture for locking the swab 'to said cross member.

3. A. mop, comprising a U-shape frame provided at the closed end thereof with an aperture, a swab adapted to be attached to the tree ends of said frame, a shank carried by said swab, and a pivoted latch mounted in said shank to be engaged with the mar gms of said aperture whereby the swab is locked to the frame.
